E46 M3 SMG Fluid Tank Leak repaired.... now clutch slipping!? *ERROR CODE P0700*

Back Story: About a week ago I unknowingly had a leak in my SMG Fluid reservoir and my car dropped out of gear on the highway! Lucky for me it was during traffic so I was able to stop shut the car off and turn it on again (had to do this a number of times) and limp my way off to the streets. When I did finally reach the street it dropped out of gear and was stuck on 0 and I was unable to shift it to any gear. Yellow cog light and SES light also on.

Had it towed to my mechanic and he fixed the leak, everything seems to be working fine now but I've noticed my transmission grabs the gears slow as if the clutch is slipping. Also he was unable to get rid of the Yellow Cog & SES light. (ERROR CODE P0700)

Prior to this my gear changes were nice, quick and grabbed hard so I don't think its the clutch?

ANY IDEAS?????

Additional info:
-Compression springs already changed
-Salmon Relay already changed
-SMG Fluid now at its correct level
-Tried the dual paddle reset, did nothing

1. Get INPA (on an XP laptop) and an OBD2 cable
2. Bleed System (the final part of the slave cylinder bleed is a clutch bite point reset)

Is it possible to do this with a PA Soft / BMW Scanner v1.4?

It's on top of your intake manifold, if your going to check the fluid level the cap is usually on there pretty tight so you may need to use a big screw driver and rubber hammer to lightly tap the cap to loosen her up.

Managed to get INPA installed onto a older Laptop I had laying around with XP, ran the program to bleed the system but it still shows the "SES" & "Yellow Cog" light?? But I did notice the shifting got better!? Weird

I didn't run the "F3 Complete Adaptation" though since I've read not to do it if I had a old clutch..... Should I just run the last step? Or do I have to do the first two again before I do?

I ran the Complete Adaptation on mine but this was all after I'd installed a new SMG pump motor. My M3 is just under 100k miles

I just found that the P0700 error means 'EGS Control Module, internal fault' and relates also to INPA code 53 which means there is a low level of pressure in the SMG pump.

Can you check the Analog values in INPA and see what your pump pressure is? If the 40A fuse next to the salmon relay hasn't blown then my best guess is you need to replace the pump motor like I did. My INPA errors were 53 and 56.

run all the steps. The clutch is self-adjusting so even if you are lower on clutch disc material this is exactly why you run all the steps. Bet that will fix everything if you've bled it and have fluid in the reservoir.

Where did you read not to to run the adaptations if you have a(n) old clutch ? I'm interested to know their reasoning or the lack of it.

Did you clear the errors for the transmission before you ran the adaptations?

Yeah I cleared it when I ran the adaptations but it re-appeared once I started the Car

I read not to do the last step on bimmerforums ( https://www.bimmerforums.com/forum/s...pump-with-INPA )

But **** it I'll just run the last step since I know my clutch is still good
Question though... should I run the whole process again or just the last step?

Thanks for the link.
I've run the full adaptations in INPA several times with no problems at all. In fact I would recommend running the adaptations about every 10,000K to detect any 'drift' in the values it measures and bring things back to spot on. Furthermore Its neccessary to run the adaptations if you change any of the sensors or mechanical SMG parts or if you change the controller.
Make sure you have a reasonable battery charger - mine draws about 9A for the duration of the process which usually goes over time by a couple of minutes.
Also make sure your INPA cable reflects the ignition status. The black dot at the top of the INPA screen should go on and off with the key.

Whats up guys, So I've finally got around to running the last adaptation and everything looks to be good.... No codes and everything seems to be in good working order. Will update in a few days to let you all know if the error lights come back.
